The present document is part of a TS-family covering the 3rd Generation Partnership Project: Technical Specification Group Services and System Aspects; Telecommunication management; as identified below:

The present document is part of an Integration Reference Point (IRP) named "Signalling Transport Network (STN) interface NRM IRP", through which an "IRPAgent" (typically an Element Manager or Network Element) can communicate Configuration Management information to one or several "IRPManagers" (typically Network Managers) concerning Signalling Transport resources. This IRP comprises a set of specifications defining Requirements, a protocol neutral Network Resource Model (NRM) and corresponding Solution Set(s). The present document specifies the protocol neutral STN interface NRM IRP. It reuses relevant parts of the generic NRM in TS 28.622, either by direct reuse or sub-classing, and in addition to that defines Signalling Transport specific Managed Object Classes. In order to access the information defined by this NRM, an IRP IS is needed, such as the Basic CM IRP: IS (TS 32.602) or the Bulk CM IRP: IS (TS 32.612). However, which IS is applicable is outside the scope of this document. Finally, regarding the support of the State Management IRP: IS (TS 28.625), all NRMs of one release shall support the same State Management IRP version.

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

• References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
• For a specific reference, subsequent revisions do not apply.
• For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
